Methodology Data on these rankings was gathered between December 4 and December 6, 2012. Three metrics were considered for each U.S. Senator: total Twitter followers, total tweets the Senator has tweeted, and total mentions on Twitter including the politician’s handle within a 24-hour time period. Each of these three metrics were given a weight. We gave total Twitter followers a weight of 50% significance. We gave total tweets the senator has tweeted a weight of 30% significance. Finally, we gave total mentions within a 24-hour time period a 20% weight. —
